Fluoruma City

Fluoruma City is a cavern city built inside the northeastern part of Mt. Cragonos, between Routes 13 and 14. The sixth gym in players' journey is located here. Even with insufficient sunlight and photosynthesis, plants and mushrooms still grow around the city. Despite being built inside a cave, there is a hole on top, allowing players to use HM2 Fly.

Fluoruma Gym
Fluoruma Gym is the northernmost building in the city. It is a garden with many platforms. As the bridge for Gym Leader is down, players have to gather various kind of fruits and put them into the basket in the centre, in order to balance the weight and reconnect the bridge. Some platforms require players to collect certain materials to build bridges.

Gym Leader Fissy is a -type specialist. Players are warned that Fissy's party has a significant increase on level comparing to the teams of all other Gym Trainers inside, and his last Pokémon is capable of Mega Evolution. Also, this is the first time that a Roria Gym Leader is fought in a Full Battle. Once defeated, he awards the player with Harvest Badge, as well as TM22 Solar Beam.

Once the player leaves the Gym after victory, Rival Tess along with Gerald arrive in the city and approach the player. Tess updates the player with what Gerald has confirmed about Team Eclipse, while Gerald gives the player HM8 Rock Climb and advises the player to continue his or her way to Frostveil City and later on, Port Decca. Tess then proceeds onto Route 14, while Gerald returns to Anthian City.

Trivia

 * The power source of Fluoruma City was collected from a waterwheel before, but it was unstable because once the water flow became weak, there would be a power outage. Later on the power is switched to be supplied from those crystals on Route 13.
 * Fluoruma Gym Leader Fissy is based on NewFissy -- creator of Treelands and Roblox Plague. The Gym is based on Treelands.
